OK, thanks. Sorry for the slow reply on this. I think you posted the same (or a related) patch a while back and it wasn't reviewed. I was a bit reluctant to say anything because it sounds like this was defined for a reason, perhaps to avoid treating the current expansion as ABI without further testing. But if it has been used for some time in Ada (and works) then it's already de facto ABI. And it seems very unlikely that anyone would spend time trying to tweak the expansion for other languages.
